Definitions

  • the subject invention relates generally to electronic throttle control device for a vehicle pedal assembly.
  • the electronic throttle control includes a resilient member interacting between the housing and a pedal portion to generate a hysteresis effect that reduces the amount of force that has to be applied to a pedal pad to maintain the vehicle at a constant speed.
  • the invention relates to foot pedal devices for controlling engines without the need for a direct mechanical connection between the pedals and the engines.
  • the invention is particularly directed to providing a drive-by-wire system, i.e., driving by electrical or electronic means, rather than by mechanical links.
  • accelerator pedals are used to mechanically control a vehicle engine and usually include a pedal mounted to a vehicle body with a series of links and levers, or Bowden cables, connecting the pedal to the carburetor, fuel injector, controller, or other similar device.
  • These linkages must be designed to withstand and accommodate engine movements relative to the vehicle frame, as well as to provide accurate control despite such movements.
  • packaging space must be provided for the linkages to function properly. The space available for routing the mechanical control links, rods, and cables is limited.
  • the pedal system In drive-by-wire applications, it is important that the pedal system provide the customary feel and performance of a mechanical linkage.
  • the pedals must function responsively to driver input and must provide non-fatiguing resistance.
  • Drivers are accustomed to applying and releasing pressure on a pedal arrangement and become accustomed to the resistance to application of force to the pedal as well as to the rate of withdrawal as the applied pressure is relaxed.
  • the customary feel during the application of force to increase speed and while maintaining speed, as well as the familiar deceleration movement of the pedal can be duplicated in a wire type control.
  • the pedal pressure required when advancing the accelerator pedal is greater than that required to maintain a fixed position. This difference is often referred to as a hysteresis effect.
  • This effect is important in maintaining the accelerator pedal in position while driving at a relatively constant speed, and it must also be considered in achieving a desired deceleration time.
  • the pressure which must be applied in accelerating is easily borne but if the back pressure of an accelerator spring produced the same effect during the time it was required to retain or maintain speed it would soon become uncomfortable for the driver to maintain a relatively constant speed.
  • the hysteresis effect provides relief. It lessens the load required to maintain a setting of the accelerator yet there is still force to cause reverse pedal action when the applied pressure is removed.
  • the hysteresis effect is also important for eliminating undesirable accelerations and decelerations as the vehicle is driven over a bumpy road.
  • Vehicles with manual transmissions do not typically include an accelerator pedal with a hysteresis effect.
  • the driver's foot follows the terrain causing the vehicle to accelerate and decelerate, which is undesirable.
  • hysteresis is needed to provide stability to the vehicle over rough terrain.
  • Wire type throttle control for vehicle engines with hysteresis generating mechanisms are known.
  • One such example is shown in United States Patent No. 5,408,899.
  • Often these hysteresis generating mechanisms are complex, include a significant number of parts, and are difficult to assemble.
  • the present invention provides an electronic throttle control with an improved hysteresis generating mechanism.
  • the hysteresis generating mechanism is simplified, requires fewer components, and is easier to maintain and assemble than known mechanisms.
  • a pedal assembly includes a housing and a pedal arm pivotally connected to the housing.
  • a hysteresis effect is achieved by using a resilient member that interacts between the pedal arm and the housing.
  • the resilient member is forced into frictional contact with a portion of the housing when the pedal arm is pivoted from a rest position to an operative position to reduce the spring force of the resilient member on the pedal arm.
  • the pedal assembly includes a housing and a pedal arm pivotally connected to the housing with a first end supporting a pedal pad and a second end forming a pedal pivot arm.
  • the pedal pivot arm has at least one cam lobe extending therefrom and the housing has a cylindrical collar portion recessed in the housing for receiving and retaining a coil spring.
  • the collar portion has a notch extending through the side wall of the housing.
  • the coil spring has a first distal end seated in the notch and a second distal end that is in bias contact with the cam lobe. The coil spring is forced into frictional contact with the side wall of the collar portion when the pedal arm is pivoted from a rest position to an operative position to reduce the spring force of the coil spring on the pedal arm.
  • the subject invention as shown in Figures 1-8 relates to an electronic throttle control accelerator pedal system including a pair of springs interacting between a pedal housing and a pedal pivot arm to achieve a hysteresis effect when an accelerator pedal is pressed and held down to achieve a desired speed.
  • accelerator pedals actuate the throttle body of the vehicle through interconnection of a push-pull type cable.
  • the friction between the cable core element and the surrounding conduit creates hysteresis in the system to reduce the force necessary to retain the pedal in the desired actuated position.
  • the initial force required to press an accelerator pedal to a certain position would therefore be higher than the force required to maintain the pedal in that position, which is known as hysteresis.
  • This hysteresis effect is important because it prevents the driver's foot from becoming fatigued as he or she holds the accelerator pedal down in a constant position.
  • the hysteresis effect is also important for eliminating undesirable accelerations and decelerations as the vehicle is driven over a bumpy road.
  • a non-cable actuated accelerator pedal assembly such as an electronic throttle control accelerator pedal
  • an alternative means of providing this hysteresis effect in the pedal must be utilized in the absence of the cable assembly.
  • the subject invention accomplishes the hysteresis effect by using a pair of springs which interact with the pedal pivot arm and pedal housing.
  • an electronic throttle control (ETC) accelerator pedal assembly is generally shown at 10.
  • the assembly 10 includes an accelerator pedal pad 12, a pedal arm 14, and a housing 16.
  • the accelerator pedal pad 12 is connected to one end of the pedal arm 14 and the other end of the pedal arm 14 is pivotally attached to the housing 16 by a pivot shaft or pin 18.
  • the pedal arm 14 is preferably formed from a steel or plastic material.
  • the housing 16 houses an electronic throttle control sensor 20 and a hysteresis assembly 22.
  • the housing 16 is light weight and made from a nylon or plastic material.
  • the electronic throttle control sensor 20 is supported by the housing 16 and generates an electric control signal that varies in magnitude in proportion to the extent of movement of the pedal arm 14 relative to the housing 16.
  • the use of an electronic throttle control sensor 20 eliminates the need for mechanical linkages and cables to control a vehicle engine.
  • the hysteresis assembly 22 preferably includes a pair of coil springs 24 and a pedal pivot arm 26. While two (2) coil springs 24 are preferred, it should be understood that more or less than two (2) coil springs 24 could be used.
  • the pivot arm 26 includes a pivot hole 28 through which the pivot pin 18 for the accelerator pedal arm 14 is inserted for pivotally attaching the pedal arm 14 and pivot arm 26 to the housing 16.
  • the housing 16 includes a pair of cylindrical boot or collar portions 30 formed by the housing side walls for receiving and housing the respective pair of coil springs 24. Each collar portion 30 includes a notch portion 32 extending through the side wall of the housing 16.
  • Each spring 24 includes a first distal end 34 received and retained in the respective notch portion 32 of the collar portion 30 and a second distal end 36 engaged with the pivot arm 26.
  • the pivot arm 26 includes a pair of cam lobes 38 which interact and engage the second distal ends 36 of the coil springs 24.
  • the cam lobes 38 are spaced apart and vary in height and include a rounded peak for smooth interference with the second distal ends 36 of the springs 24.
  • Each cam lobe 38 may also include a cap 40 which may by made of nylon or other low frictional resistive material to reduce the frictional wear between the cam lobes 38 and second distal ends 36.
  • Figures 1 and 2 disclose the one embodiment of the subject invention wherein the housing 16 is generally pie-shaped for receiving a self-contained type electronic throttle control sensor as shown at 20.
  • Figure 3 discloses an alternative embodiment of the subject invention wherein the housing 16 is smaller in dimension and the electronic throttle control sensor 20 is incorporated integrally into the housing 16 as a built-in component to provide a lower profile design. This is discussed in further detail in the co-pending application having serial number , filed on May 18, 1999, assigned to the same assignee as the subject application and herein incorporated by reference.
  • Figure 4 discloses the nylon or plastic cap 40 seated on the cam lobes 38 for interacting with the second distal ends 36 of the springs 24 to reduce the frictional wear therebetween.
  • the cap 40 includes a slots or grooves 42 in the center thereof for retaining the second distal end 36 on the cam lobe 38.
  • Each lobe 38 can be covered by a separate cap 40, or a cap 40 can be formed as a single piece to simultaneously cover both lobes 38.
  • Figures 5 and 8 show the coil springs 24 positioned in the housing collars 30 and the pedal arm 26 in the rest or inoperative position and Figure 6 shows the pedal 26 in the actuated position with the coil springs 24 flexed into tension against the biasing force of the coil springs 24 on the cam lobes 38 and the springs 24 pressed into frictional contact with the side wall of the housing collars 30 to cause the hysteresis effect on the force required to retain the pedal 26 in the actuated position.
  • Figure 7 discloses the integral electronic throttle control sensor 20 incorporated into the housing 16 having a sensor pad 44 and contact rotor or sensor arm 46 to send an electronic signal from the outlet 48 to the throttle body (not shown).
  • the housing 16 includes a center partition 50 mounted within the housing 16.
  • the partition 50 separates the sensor arm 46 from the coil spring 24.
  • the sensor arm 46 is mounted on the pivot shaft 18 on which the pedal arm 14 pivots.
  • the housing 16 also includes a cover 52 that attaches to the housing 16 to provide a sealed environment for the sensor arm 46 and pad 44.
  • the arm 46 and pad 44 should be free of dirt and other contaminants in order to work efficiently.
  • the cover 52 keeps the dirt from interfering in the operation of the sensor arm 46 as it wipes against the pad 44.
  • the housing 16 and cover 52 are preferably light weight and are made from a nylon or plastic material.
  • the housing 20 preferably includes a plurality of tabs 54 spaced around a circumferential lip of the housing 16.
  • the tabs 54 are inserted into corresponding openings in the cover 52 and are heat staked to fasten the housing 16 and cover 52 together. It should be understood, however, that other fastening methods known in the art could also be used to connect the housing 15 to the cover 52.
  • An epoxy sealer is also preferably placed applied between the cover 52 housing 16 for sealing purposes. Other sealing methods known in the art can also be used. O-rings (not shown) are used to seal the pivot shaft 18 within the housing 16 and cover 52.
  • the inventive hysteresis assembly could also be used in other pedal applications.
  • the hysteresis assembly could be used to provide feel and feedback for a brake pedal.
